Effect of lingonberry extract and palmitic acid on cytokine expression in human proximal tubular cells. Proximal tubular cells were incubated in the absence (control) or presence of lingonberry (LB) extracts (1:1,000, 1:500, or 1:200 dilution) for 4 h followed by incubation with palmitic acid (PA, 0.2 mM) for another 4 h. The mRNA expression of (A) TNF-α, (B) IL-6, and (C) MCP-1 were measured by using qPCR. The results are expressed as the means ± SE (n = 6). *p < 0.05 when compared with the value obtained from control cells. #p < 0.05 when compared with the value obtained palmitic acid treated cells.
